Binder



July 1.9, 1932- H. E. oLsEN BINDER Filed Jan.- 25, 1951 Patented July 19, 1932 UNITED STATES PATENT OFFICE l' HENRY E. OLSEN, 0F CHICAGO, ILLINOIS, ASSIGNOR TO W. G. LLOYD COMPANY, OF -j CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS BINDERJ Application filed January 23, 1931. Serial No. 510,798.v

This invention relates to binders and particularly binders in which an adjustable clamping member is secured to a binder post.

The primary object of the invention is to provide an improved device for adjustably locking the adjustable clamping memberror members to the binder posts. Other objects and advantages will appear as the specificw tion proceeds.

The invention is fully described in the following specification and shown in the accompanying drawing, in which- Figure 1 is a perspective view of a binder embodyingr my invention Figure 2 is an enlarged sectionalview showing the locking member in engagement with a binder post;

Figure 3 is a similar sectional view showing the locking member out of engagement with the post; and

Figure 4 is a magnified sectional and detail view, the section being taken, as indicated, at line 4 of Fig. 2.

In the embodiment illustrated, A represents the lower clamping member and B the upper clamping member. The members A and B may be provided with backs or covers A and B which may be secured to the clamping members by a flexible fabric hinge or by any other suitable means.

As shown more clearly in Figs. 2 and 3, the clamping'members A and B are provided with metal strips l which are preferably covered by fabric covers 2.l To the metal strip l of clamping member A, the binder posts 3 may be secured in any suitable manner. In the illustration given, the strip 1 of the clamping member A is provided with an internally lthreaded boss 4 which receives a reduced threaded end 5 of the binder post 3. With this construction, binder posts of any desired diameter may be used interchangeably, as long as the reduced end 5 engages the internally threaded boss 4.

The upper clamping member B is provided with openings 6 adapted to receive the binder post 3.

In order to lock the upper member B upon the binder posts, I prefer to employ the fol-y lowing construction. As illustrated more clearlyin Figs. 2 and 3, a plate member 7 is secured to the top wall of the clamping member B near each end by any suitable means, such as, for example, rivets. Near one'of the ends of plate 7, a portion fof the" metal is struck upwardly to form a pivot support 8, while at the same*v time providing an opening Qthrough which the binder post 3 may extend. As shown #more clearly inv Fig. 4, the pivot standard 8 is provided with shoulders Yl0 adapted to carry a slotted locking barl 11. A cap 12 confines the locking bar against the shoulders 10 but allows sufiicient play to permit the bar 1l to rock upon 'A the shoulders l0 as a pivot. The forward end i' of the locking bar l1 is'provided with anv s opening 13 adapted to receive yone of 4the binder .posts 3. I Y

In order to maintain the 4locking bar l1 iny engaged and disengagedv positions, I prefer'm` to employ a metal spring strip.14,.in substantially the shape illustrated. Preferably the spring 14 comprises a forwardly extending arm 15 engaging the under side of the locking bar vlluand a curved, vertical strip.` 16 adapted to engage the rear end of the locking bar. The spring 14. is also preferably provided with a rearwardly-curved upper portion 17 which serves as a means for locking the rearend of the bar 11 in raised and' lowered illustrated, the portions 16, 17 together yresemble somewhat the letter S.

Any suitable means may be used to secure the spring to the plate 7. In the illustration' given, arivet is used.

In the operation of the device, the locking member may be caused to-assume the position shown in Fig. 2'i`by drawing backthe vertical spring portions 17 and 16 so asto" permitthe forwardly extending spring arm l5, which normally urges `the lever 11 upwardly, to raise'the rear end of lever 11. -In this position, the locking member 1l is held against the binder post 3 and prevents upward movement of the clampin member P. /Vhen it is desired tounlock the members, the rear end of the lever 11 may be depressed so as to swing the locking bar 0r lever to a ,substantiallyl horizontal position. In this .for turning the posts construction. may vparting position, the member B may be raised or lowered freely along the binder posts. The horizontal position of the lever 11 is maintained against the upward Vpressure of spring arm 15 by the curved end portion 17 of spring 14.

AIn the above construction, it Will be observed that the spring 14: serves notonly to urge the locking bar 11 into locking position but also'it serves to maintain the locking bar firmly in either locked or unlocked positions. The locking structure is extremely simple, sturdy and effective in operation.

Il desired, the upper ends of the posts 3 may be provided With squared-oil indentations 18 adapted to receive a Wrench or tool 3 When it is desired to remove them Vor to insert them into the threaded bosses 4;. Y

While I have described a specific locking mechanism, it is obvious that the details of be changed Without derom the spirit of my invention.

The foregoing. rdetailed. description has been given for clearness of Vunderstanding only, and .no unnecessary limitations should be understood therefrom', but the 'appended -claims should be construed as broadly as permissible, in vievv of the prior art.

.l claim:

1. A post-binder comprising, a post, a

clamping member movably fitted thereon, a

locking member apertured at one end to receive said post, means for pivotally support- Y ing said locking member on said clamping `clamping member movably iitted thereon, a

inember, spring means for urgingsaid :locking member into contact With said post,and

Va releasable spring catch adapted to hold said locking member out of engagement with vsaid post. Y n, Y l

2. A`r post-binder `comprising, a post, a

locking member apertured at one end to receive said post, means for pivotally supportving said locking member on said clamping member, spring means for urging said locking member into engagement with said post, and a spring catch cooperating withV said spring means to releasably hold said locking member out of engagement with said post.

3. A post-binder comprising, a post, a clamping member movably iitted thereon, a locking member apertured at one end Vto receive said post, means for pivotally supporting said locking member on said clamping member, spring means for urging said lockf ymg member intoengagement With said post,

and a spring member equipped With a Cam portion adapted to releasably hold said'lockn VVing member in engagement and out of engagement with said post.

4. A post-binder comprising, a post, a clamping member movably fitted thereon, a
